Hybrid tea rose plant named `Ruitica`

ABSTRACT

A new variety of hybrid tea rose plant producing pale yellow flowers.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of rose plant of the hybrid tea rose class which was created by crossing undistributed, unnamed and unpatented seedlings as seed and pollen parents in The Netherlands. The varietal denomination of the new variety is `Ruitica`.

SUMMARY OF THE INVENTION

Among the novel characteristics possessed by this new variety which distinguish it from its parents and all other varieties of which I am aware are its attractive cream colored flowers with long stems borne on a floriferous plant.

Asexual reproduction by budding of the new variety as performed in The Netherlands, shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations. The new variety has been reproduced through propagation by cuttings, grafting, budding and micropropagation.

BRIEF DESCRIPTION OF ILLUSTRATIONS

The accompanying two photographic illustrations show the new variety of hybrid tea rose plant in color as true as it is reasonably possible to attain in color illustrations of this character.

The first illustration is a close up view of the bloom, peduncle, and foliage.

The second illustration shows a new shoot, 1; compound 3-leaflet leaf, 2; compound 5-leaflet leaf (partially cut-off), 3; compound 7-leaflet leaf, 4; a steam, 5; buds, 6 and 7; a flower about 1/3 to 1/2 open, 8; a flower fully open, 9; and flowering stems 10, 11, and 12, with reproductive organs displayed.

DESCRIPTION OF THE NEW VARIETY

The following is a detailed description of the new variety, with color terminology in accordance with The Royal Horticultural Society Colour Chart (R.H.S.C.C.) and horticultural terminology in accordance with standard terminology used in UPOV-approved horticultural guidelines. The terminology used in color descriptions herein refers to plate numbers in the aforementioned color chart. Phenotypic expression may vary depending upon growing conditions under different climate, soil, and cultivation conditions.

Parentage: Seed and pollen parents are unnamed seedlings.

Class: Hybrid Tea.

The following further horticultural description is based on observations made of specimens grown under glass in Quito, Ecuador.

(5) Color.--After sepals part and petals unfurl color of petal top surface appears near 11C to 11D with slight pink washing, near 52C to 52D, on very outer petals; center of flower where petals bunch is slightly deeper toned yellow; Petal undersurface exhibits near 62D washing and veining against near 11C to 11D. Color at point of petal attachment is near 3D. Overall tonality from a distance is pale yellow to cream flowers.

(6) Peduncle.--Generally smooth.
